Out of 525 pupils examined, 119(22.7%) were found to be excreting ova of S. haematobium in their urine, which comprised 44 females (17.5%) and 75 males (27.5%). Children between the age of 15 -16 years recorded the highest prevalence of 35.9%. Chi square test showed that the differences among the age groups are not statistically significant. The distribution of the infection was significantly high in Hill Top Primary School Amoffia Ngbo, Ohaukwu Local Government Area with the prevalence of 55.3% when compared to other locations assayed. Children whose parents were farmers recorded the highest prevalence (26.4%) when compared to those of other occupations (p<0.05). In the same vein, children that make use of quarry pit water as their main source of water supply recorded more infection than those that use _____________________________________________________________________________________________________ *Corresponding author: Email: [email protected]; Onwe et al.; IJTDH, 18(3): 1-7, 2016; Article no.IJTDH.13138 borehole and pipe-borne water.

Schistosoma haematobium is the causative agent of urinary schistosomiasis also called In the western region, S. haematobium is Bilharziasis. It is an important digenetic universally distributed. The highest infection trematode found in Middle East, Asia, Oceania rates are found in Ibadan, Oyo, Abeokuta and and Africa. It afflicts the poor, rural villagers, Epe area.

Schistosomiasis is not only endemic in District of Ebonyi State, Nigeria. Nigeria but is also known to be prevalent in all countries of Africa [2]. According to estimates of 2.

Estimates suggest that 85% of all The approximate population of the State is 2.093 schistosomiasis cases are now in sub –Saharan million (Population Census, 2006). There are Africa [4]. thirteen Local Government Areas in the state which is divided into three senatorial districts: Nigeria is one of the countries known to be highly Ebonyi North, Ebonyi Central and Ebonyi South. endemic for urinary schistosomiasis with Ebonyi North is made up of four local estimated 101.28 million persons at risk and Government areas; —Abakaliki, Ohaukwu, 25.83 million infected [5].

These include the territory The major economic activity of these people is extending from Katsina, Kano, Zaria and Kaduna agricultural farming like rice farming which keeps to the Western frontier, in the region of Birinin them in constant contact to water surfaces with Kebbi, Argungu and Kankiya areas [6].

The teachers and pupils were enlightened on the relevance of the study especially the public health significance. The 3. RESULTS method of urine collection was also explained to them. After this the pupils were randomly The result revealed that in a total of 525 selected. The children were given serial number pupils who were examined for Schistosoma and containers were distributed noting on the haematobium infection, 119 pupils were found to container
